Answer:
37.5%
Explanation:
We define first our values, that are,
We can now calculate the net power output, that is
Thermal efficiency is given by
Answer:
multiplication
Explanation:
multiply your distance of 18 kilometers by 1,000 to get 18,000 meters.
The distance from point a and point is equal for travels going back and forth. They would just differ in time and speed because of the sea's speed that propels the vessel. The solutions as as follows:
Distance upstream = Distance downstream
99(t + 2) = (99 + 1)(t)
Solving for t,
t = 198 hours
That means that the distance is equal to:
Distance = 99 miles/hour * (198 + 2 hours)
Distance = 19,800 miles

2. Need to know the direction of the displacement or change of position
When you know these 2 things, you can describe an objects velocity
